Hi,
on page 5.2 of the GS2 user manual:
P 9.00 default 01, this is the slave address, OK as is
P 9.01 default 01 transmission speed is 9600 baud, OK as is just set Modbus transmit to 9600 baud as well
P 9.02 default 00 ASCII, 7 data, no parity, 2 stop. The serial Modbus plugin of Mach3 does not have this combination, suggest 8 data, no parity,2 stop ie P9.02=03
Suggest you manully program the VFD with this parameter. You will also have to program the VFD to accept frequency and run commands from Modbus, but that
is a bit down the track yet.
The remainder of the parameters on this page do not concern us immediately.
On Page 5.3:
P 9.26 frequency command
9.27 Run/Stop value
9.28 Fwd/Rev value
While the alarm and status may prove useful in the future lets ignore them for the time being, they won't prevent us from getting the thing to run.
On page 5.8:
the decimal memory addresses:
P 9.26 42331
P 9.27 42332
P9.28 42333
Thus we have three consecutive input words.
On Function Cfg's/Setup Serial Modbus Control set up per the screen shot attached, I don't really know if I'm correct but it wont hurt to try.
